Estimated running cost = annual kWh × 18.31¢/kWh (July 2026 US average). Your own rate may be higher or lower — check your bill. ENERGY STAR figures are lab-test results; real-world use varies. This list includes discontinued and not-yet-sold certified models, and some brands are white-label relabels of the same unit.
